ABSTRACT:
There is provided an electron gun which has an assembly precision improved by the reduction of deformation of an electrode during assembly as well as good focusing performance due to the elimination of positional deviation of electron beams. There is also provided a method of assembling such an electron gun. The electron gun comprises a composite electrode including at least two electrode elements united together and a plurality of electrodes sequentially arrayed along a single axis at predetermined intervals. In the electron gun, opposed faces of the electrode elements of the composite electrode are perpendicular to the axis and the opposed faces are provided with projections 1a and 1b which serve to constitute the composite electrode when the projections are united together in opposed relationship to each other.
